Acesta este un amplificator setereo complect cu schema electrica si circuitul imprimat pentru puteri de pana la 2X15W.Foloseste minimul de componente impreuna cu TDA7297 de ST Microelectronics.
Circuitul integrat TDA7297 are la interior doua amplificatoare legate in punte cea ce il face ideal atunci cand este nevoie de un amplificator stereo usor de construit.
Poate functiona cu Tensiuni de la 6V pana la 18V si are protectie termica impotriva supraincalzirii.
Despre amplificator:
- Suporta o plaja mare de tensiuni:6-18V.
- Componente externe putine.
- Stand-by si Mute.
- Protectie la scurt circuit.
- Protectie termica.
